METHODS OF TIME SERIES DYNAMIC PREDICTION OF ROAD EMBANKMENT SETTLEMENT
Leng Wu-ming · Tiedao gongcheng xuebao · 2004
The roadbed settlement which is influenced by many complicated factors is a dynamic and dependent process.During the filling construction of the roadbed the total settlement value could be predicted by using time series equal interval prediction model of recent information. With the addition of new deformation datum the model parameters are continuously modified. The practical settlement prediction of the abutment embankment has showed that the error between measure and one-step prediction value is mostly below 5mm of 2.3mm average error absolute value. The more prediction step is the more error is.
